What resources are available to manage these stresses and support the sisters while caring for their dying sister Sandra? 

Numerous resources are available to support the sisters and help them manage their stress. They can first access counseling from professionals who are experts in the field of mental health, such as psychiatrists, psychologists and social workers. They can provide advice about how to deal with the psychological and emotional distress of caring for someone who is terminally ill. There are online support groups that organizations like The National Hospice and Palliative Care Organization run to help people vent frustrations and exchange experiences with other individuals going through the same situation.

They can also consider hospice services that provide respite and other types of assistance to help make the life easier for caregivers as well as patients during this trying time. Finally, it is important that the sisters take time for themselves in order to rest and recuperate – be it spending time outdoors, engaging in relaxing activities like yoga or reading, or simply talking about their worries with close friends or family members; these small steps can go a long way towards helping them find peace amidst all the chaos.
